What version of the product are you using? On what operating system?

The fault occurs with the binary 1.0 and 1.01 distributions, as with the src 
1.01 distribution.

harvey:~/Development/galago-test$ uname -a
Darwin harvey.cs.umass.edu 9.6.0 Darwin Kernel Version 9.6.0: Mon Nov 24

Core Solo 1.5GHz, 2GB memory.
Please provide any additional information below.
The fault does not occur on linux:

This appears to be a race where the top-level index directory has not yet been 
created when the 
DocumentNameWriter is instantiated. Creating the top-level index directory 
manually prior to 
running galago  resolves the FileNotFoundException issue and enables a 
successful index build.

I also had the issue on Ubuntu 8.10, following the quickstart instructions for 
Galago
1.01 binary distribution.
